Abstract/Description: | Viral diseases cause havoc on crop yield, both qualitatively and quantitatively. Geminiviridae is the largest family of plant viruses and constitutes an important group of plant pathogens with genomes of ssDNA. Geminiviruses are characterized by particle morphology of twinned incomplete icosahedra. Geminiviruses derived their name from unique structure and geometry of virus particles, where two icosahedrals are joined together. Family Geminiviridae is further classified into nine different genera on the basis of nature of genome, host plant infection, and vector requirements for disease transmission. These viruses cause significant yield loss to economically important plants. Disease outbreaks on cotton, cassava, tomato, and other important horticultural plants were reported to have major crop loss due to virus infection. Further, molecular interactions and presence of satellite molecules enable virus particles to break innate immunity of plants and revoke disease outbreaks. Also introduction of exotic species, transfer of plant materials across continents, and vector migration are also important factors which contribute to widespread distribution of geminiviruses. India and the Indian subcontinent have experienced and are experiencing major loss due to infection by geminiviruses. Novel recombinant viruses, host switching, and newer satellite molecules continue to be reported from the Indian subcontinent. Tropical humid atmosphere and crop diversity are major factor for vector multiplication and hence virus transmission too. This chapter reviews the major geminiviral crop infections in the Indian subcontinent. |
